This information applies to HP and Compaq desktop computers with the Cleveland motherboard.

The Cleveland motherboard uses an AMI BIOS version 7 that is compatible with UEFI (Unified Extensible Firmware Interface).

The Basic Input Output System (BIOS) is responsible for enabling the hardware system on your computer when the computer is turned on. The Computer Setup Utility makes it possible to change and store system configuration settings such as enabling and disabling onboard components, setting the boot sequence for the system, and adjusting power management support.

Turn on the computer and immediately press the F10 key repeatedly, about once every second, until the Computer Setup Utility opens.

Turn on the computer and immediately press the Escape key repeatedly, about once every second, until the Startup menu opens. Then press F10.
